APCUltrafiltrationMembranes

ltrafiltration or UFis a pressure- drivenmembrane separation process thathelps to remove particulate matter

from aqueous solutions such as water.

APC UF membranes typically have pore sizesin the range of 0.03 m and efficiently removebacteria and most viruses, colloids, turbidityand silt. Materials that are used in UF arepolymeric and are naturally hydrophilic.

APC UF membranes are made from high-grade Polyethersulfone (PES)-based sevenpore membrane fibers material to form ahollow fiber membrane that is very durableand less prone to breakage. The hollow fiberhas a dense layer or skin on both the insideand outside surfaces, forming a double-walled structure that contributes to itsstrength. All membranes are assembled inone bundle rigidly fixed onto potting resinsand protected by a PVC housing.

APC UF membrane fouling resistance is improved by making the membrane surface morehydrophilic. With uniform pore size and inside-out flow, the UF membrane creates a barrierwithout sacrificing performance.

APC UF membranesutilize a double-walled hollow fiber membrane with a very small porediameter for excellent removal of particulate matter and bacteria, and most viruses and colloids.
